Technical Abstract

An approach and device for optimizing a sound system by extracting a two-channel stereo source out of a set of multiple channels with unknown frequency responses, crosstalk, time delays and sample rate by employing a digital test sequence that utilizes maximum-length-sequences (MLS) that is fed into the sound system and results in a reconstructed stereo source that may be further used as an input to a signal processor that performs improved speaker and room equalization.
